Types of Corrugated Materials

Single Faced fibreboard is constructed by gluing a flat sheet of linerboard to a sheet of corrugated material which has been passed through a single facer, thus forming it into a series of arches. This ensures that the corrugations will be firm and will not stretch or flatten.

Singlewall corrugated fibreboard consists of two flat facings and one corrugated member combined in the sequence that follows: a facing, a corrugated member, and another facing.

Doublewall corrugated fibreboard consists of three flat facings and two corrugated members combined in the sequence that follows: a facing, a corrugated member, a centered facing, a corrugated member, and a facing.

Triplewall corrugated fibreboard consists of seven sheets of paperboard combined in the following sequence: a facing, a corrugated member, an inner facing, a corrugated member, an inner facing, a corrugated member, and a facing.
